Definitions
- This invention relates to an urban transportation apparatus capable of use in an urban transportation system.
- this invention relates to a safety device for minimizing damage to suspended coaches and passengers and cargo therein in the case of collision between coaches located on the same rail track.
- buses also utilize the highway network, but are far less popular than automobiles. Buses are less favoured than automobiles because one must often wait at a bus stop for a relatively long period of time and in potentially disagreeable weather. Further, buses are generally restricted to particular routes, and consequently a bus rider must walk, or acquire other transportation, to and from bus stops along various routes proximate to his origination and destination. Frequently, transfers must be made from one bus to another due to inadequate routes, and frequent interim stops must be made to load or unload other passengers. Still further, buses are subject to many of the same drawbacks as the automobile, such as traffic, stop lights, and traffic risk. As a result, buses are not as popular as the automobile even though, when properly utilized, buses are more efficient and less environmentally harmful than the cumulative effect of so many individual automobiles.
- Rail-guided vehicles such as trains, monorails, and subways
- Rail-guided vehicles are an alternative transportation system found in many cities and urban areas. When properly utilized, such systems are more energy efficient than automobiles and less environmentally damaging.
- rail guided vehicle users are dependent upon predetermined and often inadequate schedules, a limited number of fixed routes, and lost time due to stops at intermediate stations for other passengers.
- Even the relatively high speeds attained by rail-guided vehicles do not fully compensate for the time lost in other ways when using such transportation systems.
- Surface railway is impossible to lay in an existing city. But even to lay the same in a new development is subject to negative implications. The development remains divided by the corridor and it a permanent noise polluter.
- Underground railway is less invasive on the surface but still poses technical challenges including the management of fires and evacuation. If road vehicles are involved in inter-modal transfers, it becomes a weak link in the chain of transport between walking and the railway.
- Elevated railway technically cannot reach congested central busy roads where mass transport is needed. It is too invasive and may require dislocation of some portions of the habitat as well as the system is very noisy.
- DE-C-99412 describes a beam suspended from a bogie having wheels for running along a rail.
- Four capsules are pivotally attached to the beam and are connected together at their lower ends.
- a locomotive is described which pushes against the beam to push the capsules to the top of high slopes.

Since the coaches are removably connected, this permits fast and efficient removal and replacement of the coaches with other coaches or with load carrying cargo carrying means, if desired.
- the bogie may be secured to a suspender beam via a connecting steel load transfer beam and spring loaded bolsters, to dampen the jerks and other movements from the rails to the bogie wheels.
- the bogies are also secured to the suspender beams via means of central pivots which permit controlled play and limited angular displacement of the bogie assembly on the suspender beam, if necessary.

Abstract
Description
- This invention relates to an urban transportation apparatus capable of use in an urban transportation system.
- In our co-pending Indian application 715/mum/2001 there is disclosed a transportation system, capable of providing high capacity lateral transportation in downtown core areas.
- Particularly, this invention relates to a safety device for minimizing damage to suspended coaches and passengers and cargo therein in the case of collision between coaches located on the same rail track.
- All over the world, populations are rising and the infrastructure development is not keeping pace. The roads are unable to handle the rising number of vehicles and metro rails face inadequacies in increasing the capacity, besides the risk of vandalism and derailment. Expansions or new constructions need land in urban areas, which is not possible; alternative underground railways are too expensive. Transportation is a critical element in the smooth and efficient operation of almost every aspect of today's cities and urban areas. As a result, many types of transportation systems have been developed to move people and cargo from one place to another more efficiently. The most prominent transportation systems are overland travel by automobiles and bogies, both operating on roads such as public highways. Public buses utilize the same highway network, as do, to some extent, cable cars and electric buses. Conventional high capacity urban transportation systems generally employ underground trains or streetcars moving along conventional rails. Such systems take up a considerable amount of space in the urban area and do not allow the individual cars to be separately directed. Subways, monorails, and trains, however, utilize a rail network that is typically less developed than the surrounding highway networks. Other forms of inter-city transportation include the bicycle, auto rickshaws, scooters and motor cycles, all of which use the same roads. Consequently the roads are unable to handle the rising number of vehicles.
- Public buses also utilize the highway network, but are far less popular than automobiles. Buses are less favoured than automobiles because one must often wait at a bus stop for a relatively long period of time and in potentially disagreeable weather. Further, buses are generally restricted to particular routes, and consequently a bus rider must walk, or acquire other transportation, to and from bus stops along various routes proximate to his origination and destination. Frequently, transfers must be made from one bus to another due to inadequate routes, and frequent interim stops must be made to load or unload other passengers. Still further, buses are subject to many of the same drawbacks as the automobile, such as traffic, stop lights, and traffic risk. As a result, buses are not as popular as the automobile even though, when properly utilized, buses are more efficient and less environmentally harmful than the cumulative effect of so many individual automobiles.
- Rail-guided vehicles, such as trains, monorails, and subways, are an alternative transportation system found in many cities and urban areas. When properly utilized, such systems are more energy efficient than automobiles and less environmentally damaging. However, many of the same drawbacks exist for rail guided vehicles as for buses. For example, rail guided vehicle users are dependent upon predetermined and often inadequate schedules, a limited number of fixed routes, and lost time due to stops at intermediate stations for other passengers. Even the relatively high speeds attained by rail-guided vehicles do not fully compensate for the time lost in other ways when using such transportation systems. Surface railway is impossible to lay in an existing city. But even to lay the same in a new development is subject to negative implications. The development remains divided by the corridor and it a permanent noise polluter. Sudden disgorging of heavy loads of commuters at stations creates needless congestion on the roads reducing the quality of life. Several thousands of persons die annually because of trespassing or falling from trains. In addition derailments, collisions and capsizing cause serious damage to life and limb and property.
- Underground railway is less invasive on the surface but still poses technical challenges including the management of fires and evacuation. If road vehicles are involved in inter-modal transfers, it becomes a weak link in the chain of transport between walking and the railway.
- Elevated railway technically cannot reach congested central busy roads where mass transport is needed. It is too invasive and may require dislocation of some portions of the habitat as well as the system is very noisy.
- Consequently, cities and urban areas have been plagued by the problems associated with having private automobiles as the primary mode of civilian transportation. A person will readily spend hours in heavy traffic either because there is no alternative, or because any available alternatives require more time and inconvenience. Moreover, the pollution created by millions of private automobiles is having an immeasurable effect on the environment and quality of civilian life, not only in urban areas but in the surrounding rural areas as well. The cumulative energy wasted at stop lights and in traffic is considerable, and causes a direct increase in fuel costs and other costs associated with automotive transportation. The energy required to accelerate an automobile that weighs several thousand kilograms is frequently converted into little more than friction within the automobile's braking system at the next traffic light. This is a considerable amount of wasted energy since the average human occupant in a typical automobile represents a mere 5% of the gross vehicle weight. Still further, dependence upon extremely large amounts of fossil fuels to power a large automotive transportation system makes such a society somewhat vulnerable to the whims of those who possess fossil fuel reserves.
- Clearly, then, there is a need for a public transportation system that is able to compete with the automobile in terms of convenience to the user, but does not require the tremendous energy consumption of an automotive transportation system. Further, such an improved transportation system should provide increased safety expectations, less overall cost to the user, and profitability to those manufacturing, owning, and operating such a system. All administrations are in search of an economical viable solution to the transportation problem, which is concomitantly environment friendly.

DE-C-99412 describes a beam suspended from a bogie having wheels for running along a rail. Four capsules are pivotally attached to the beam and are connected together at their lower ends. A locomotive is described which pushes against the beam to push the capsules to the top of high slopes. Said known transportation apparatus corresponds to the preamble of claim 1. - The present invention relates to a public transportation system that fulfills the above needs and provides further related advantages.
- An object of the present invention is to improve the versatility of the urban transportation system by providing devices that can be used for clearing an immobilized suspended coach unit, which has hitherto been impossible using systems of the prior art.
- According to one aspect of the present invention there is provided urban transportation apparatus capable of use in an urban transportation system, the apparatus comprising:-
- a suspender beam for suspending a coach unit below rails on which the coach unit traverses in the urban transportation system;
- According to another aspect of the present invention there is provided a method of clearing a coach unit which is immobile or derailed, the coach unit having a suspender beam for suspending the coach unit below rails on which the coach unit traverses in an urban transportation system, the method comprising the steps of:-
- moving a mobile suspended coach unit as defined herein above towards the immobile or derailed coach unit so that the extremities of the suspender beams of the immobile or derailed coach unit and the mobile coach unit abut;
- operating the extensor and lifting mechanism of the mobile coach unit to extend below the extremity of the suspender beam of the immobile or derailed coach unit and to lift the suspender beam of the immobile or derailed coach unit so that wheels of the immobile or derailed coach are effectively above the rails on which the coach units traverse; and
- moving the mobile coach unit together with the immobile or derailed coach unit secured thereto to clear the immobile or derailed coach unit.
- Thus, the present invention enables quick and efficient clearance of unserviceable and failed bogie units attached to immobilized coach units in suspended coach rail transportation systems.
- The present invention can be applied to a suspended coach transportation system comprising an extended continuous hollow box way having a slot throughout its operative under wall, said box way being elevated by columns from the ground level and generally following the lay of the ground; a pair of rails fixed on either side of the slot on the operative inner surface of the under wall within the extended box way and extending continuously throughout the box way; a plurality of bogie assemblies moving on the said rails within the box way; removably mounted coaches suspended from suspension means extending through the slot in the box way, the bogie assemblies being generally connected to the coach suspension means in a manner that permits controlled longitudinal, swinging and angular displacement of the coaches and their suspension means. Since the coaches are removably connected, this permits fast and efficient removal and replacement of the coaches with other coaches or with load carrying cargo carrying means, if desired.
- In such a coach transportation system, the bogie may be secured to a suspender beam via a connecting steel load transfer beam and spring loaded bolsters, to dampen the jerks and other movements from the rails to the bogie wheels. The bogies are also secured to the suspender beams via means of central pivots which permit controlled play and limited angular displacement of the bogie assembly on the suspender beam, if necessary.
- The coach unit defined above may comprise a single-coach.
- Examples of the invention will now be described with reference to the accompanying drawings, in which:-

Figure 5 shows schematic details of the method of clearance of an immobilized coach unit by an assisting coach unit. -
Figure 6a and 6b show a schematic end detail of a suspender beam. - Referring to the drawings,
Figure 1 shows a schematic sectional view of a suspended coach transportation system in accordance with this invention. - The transportation system generally indicated by the
reference numeral 10 comprises an extended continuoushollow box way 12 having aslot 14 throughout its operative under wall.Columns 16 elevate thebox way 10 from the ground level and generally following the lay of the ground. A pair ofrails 18 are fixed on either side of theslot 14 on the operative inner surface of the under wall within the extendedbox way 12. The rails extend continuously throughout the box way. A plurality ofbogie assemblies 20 move on the said rails 18 within thebox way 12. - Removably mounted
coaches 24 are suspended fromsuspension shafts 26 extending through theslot 14 in thebox way 12 and secured to asuspender beam 30. Thebogie assemblies 20 are generally connected to suspender beams. The coach suspension means permit controlled longitudinal, swinging and angular displacement of thecoaches 24 and their suspension means. - The
box way 12 is a concrete box way and an array ofcentral columns 16 support two extending box ways on either side of the columns as seen inFigure 1 . Thesebox ways 12 permit traverse of suspended coaches along the box ways on either side and alongside of the columns, typically in opposite directions. - As seen in the Figures, the
box way 12 has a generally rectangular or square cross section defined by a pair of horizontal and a pair of vertical walls typically of concrete said walls enclosing a space; one of said horizontal walls, typically the under wall of the box way defining acontinuous slot 14. - The extended box way is constructed by aligning and joining a plurality of pre fabricated box way segments secured to the columns. The box ways on either side of the columns are integral with each other.
- The
columns 16 are typically 1m-diameter columns 8m high spaced apart by a distance of advantageously 15m with respect to each other and formed in the divider space between the carriageways on a roadway. - Typically the
coaches 24 are suspended at a height of 2m to 4m above the road surface/ground level. - The
rails 18 are fitted in an elastic medium dampened by inertia of measured mass. - Conventional rails used for over ground railways are used as the guiding rails in the box ways.
- The
bogie assembly 20 is secured to asuspender beam 30 via a connecting steel load transfer beam and spring-loaded bolsters, to dampen the jerks and other movements from the rails to thebogie wheels 36. Thebogies 20 are also secured to the suspender beams 30 via means of central pivots, which permit controlled play, and limited angular displacement of thebogie assembly 20 on thesuspender beam 30, if necessary. - The
coaches 24 are suspended from thesuspender beam 30 by a plurality ofsuspender shafts 26. - The coaches are removably connected the suspension shafts, which permits fast and efficient removal and replacement of the coaches with other coaches or with load carrying. Cargo carrying means, if desired. Thus the coaches are coupled to the bogie assemblies indirectly. The central pivot type coupling between the bogie assembly and the suspender beam provide controlled limited angular displacement and swing in a direction perpendicular to the direction of motion.
- The
coaches 24 are preferably passenger cabins connected indirectly to the bogie assemblies by a rotational coupling that allows the passenger's cabin to remain in the vertical orientation while the attitude of the bogie changes. - Referring to
Figures 3 and 4 , the collision protection method further provided in accordance with this invention involves increasing the length of the suspender beams 30 to be longer than thecoach units 24 suspended below, so that if acoach unit 24 were to ram into another, the suspender means ends 32 take the impact of the collision by first damping and then absorbing the impact energy in the region Z marked infigure 3 . In any case direct impact between the coaches is prevented. As seen inFigure 4 , the impact absorbing ends 80 have a impact absorbing region 'd' which is typically 2.5 m spaced apart. For the ends of the coaches to come into contact they will have to travel a distance 2.5 m after the elastic absorption of impact energy. - At the ends 80 are provided
impact damping elements 82 secured to the suspender beams 30 via spring loaded shock absorption means, which damp the impact energy. The ends 32 are made of deformable material, such as for example of hollow metal sections which after full elastic retraction of the dampingelements 80 deformable crush. It is only then that the solid steel bar beams come into contact. As seen inFigure 3 , the effective distance between the coach units is 2.5 metres when the ends 32 abut each other on impact. The suspender beams 30 will have to be crushed by this distance before thecoaches 24 actually touch which is not likely even at the highest possible speeds attainable by each coach unit. - Referring to
Figure 5 , the immobilized or derailed coach clearance means provided in accordance with this invention involves increasing the length of the suspender beams 30 to be longer than thecoach units 24 suspended below, so that if acoach unit 24 were to ram into another, the suspender beam ends take the impact of the collision and absorb the impact energy. In any case direct impact between the coaches is prevented. - The suspender beam ends are also used for clearing an immobilized coach unit ICU with the help of an assisting coach unit ACU as seen in
figure 5 . The assisting coach unit ACU is displaced towards the immobilized coach unit ICU until the ends of the suspender beams are aligned. The end of the assisting coach unit ACY is then displaced to lie under the end of the immobilized coach unit ICU as seen inFigure 5 . The end and therefore the suspender beam of the immobilized coach unit is raised. This action lifts the bogie wheels of the immobilized coach unit off the track and the assisting coach unit ACU can then push the immobilized coach unit for clearance. - A typical example of the extensor and
lifting mechanism 40 is seen inFigures 6a and 6b where the end ACY of asuspender beam 30 has alower plate 40 which can be extended and bent to raise the suspender beam of an immobilized coach. - The coach and bogie configuration is unique in its function of mobility, directional control, track interface, suspension, and flow extraction. The clearance method is also unique in its structural simplicity, universality of application in the transport sphere, and its passive operation.
